If you walk into a crowded room in Beijing and yell "Nǎinai," exactly half of the grandmothers in the room will turn around. The other half? They’ll keep sipping their tea like they didn't hear a thing. Honestly, if you grew up in a Western household where "Grandma" covers everyone from your dad's mom to that nice lady down the street, the Chinese system is going to feel like a linguistic obstacle course. Mandarin doesn't just have one word for grandma. It has a specific map based on bloodlines, geography, and even how much your family cares about old-school etiquette.
Most beginners think they can just grab a dictionary, find one word, and call it a day. Big mistake.
In Chinese culture, hierarchy is everything. The language reflects this by distinguishing between the "inside" family (your father's side) and the "outside" family (your mother's side). It sounds a bit harsh to modern ears—calling your maternal grandma an "outside" grandmother—but it’s baked into the DNA of the language. If you get it wrong, you’re not just making a typo; you’re basically misidentifying your own lineage.
The Paternal Side: Meeting Your Nǎinai
When people ask how to say grandma in Mandarin, the most common answer you’ll hear is Nǎinai (奶奶). This is specifically your father’s mother. It’s the "official" version taught in most textbooks.
In a traditional Chinese household, the paternal grandparents were the ones you lived with. You’d see them every single day. Because of that proximity, Nǎinai carries a sense of authority and domestic presence. It’s a soft, repetitive sound—third tone followed by a neutral tone—that feels affectionate but respectful.
But wait. If you’re in a formal setting, or perhaps writing a letter, you might use Zǔmǔ (祖母). Nobody actually says "Zǔmǔ" when they’re asking for more dumplings at dinner. That would be like calling your grandma "Maternal Matriarch" while watching TV. It’s stiff. It’s for family trees and legal documents.
Interestingly, regional slang messes with this. In some parts of Northern China, you might hear people use "Nǎi" as a shorthand, but sticking to the double syllable is safer for learners. It sounds more natural. Using the single syllable can sometimes come off as blunt or even rude if your tone isn't perfect.
The Maternal Side: The "Outside" Grandmother
Now, let’s talk about your mom’s mom. This is where things get tricky because China is massive, and regional pride is a real thing.
The "standard" Mandarin term—the one you’d use for the HSK exam—is Wàipó (外婆). That "Wài" literally means "outside." Historically, once a woman married, she "left" her family to join her husband’s. Her children were considered "outside" relatives to her parents.

Is it outdated? Maybe. Do people still use it? Constantly.
However, if you find yourself in Beijing or anywhere in the North, saying "Wàipó" might get you some funny looks. Northerners almost exclusively use Lǎolao (姥姥).
I remember a friend from Harbin who moved to Shanghai. She kept calling her grandmother Lǎolao, and her Southern friends thought she was using some ancient dialect. In reality, Lǎolao is the heart and soul of Northern Mandarin. It feels warmer, more rhythmic. If you’ve ever watched a C-drama set in Beijing, you’ll hear the kids screaming "Lǎolao!" when they run through the door.
Why the distinction matters
You might wonder why we can't just pick one.
Chinese is a language of relationships. When you use the correct term, you are instantly telling everyone in the room exactly how you are related to that person. It eliminates ambiguity. If I tell a friend, "I’m going to see my Wàipó," they know immediately I’m headed to my mother’s side of the family. There’s no need for follow-up questions. It’s efficient, even if it feels like a lot of memorization at first.
Regional Variations: Beyond the Textbook
Mandarin isn't a monolith. China has dozens of dialects, and even within "Standard Mandarin," the local flavor changes the vocabulary.
Take Taiwan, for example. In Taiwan, and among many Southern Chinese communities, you’ll frequently hear 阿嬷 (Ā-mā). It’s technically Minnan (Hokkien), but it has bled into the local Mandarin so deeply that everyone uses it. It’s incredibly casual. It’s the kind of word you use for a grandma who wears a floral apron and spends all day in the kitchen.
Then you have the Cantonese influence. While not Mandarin, the term Pòpo (婆婆) is often used in Mandarin-speaking circles in the South to refer to the maternal grandmother. But be careful—in some contexts, Pòpo can also mean "mother-in-law" (specifically the husband’s mother).

Imagine the confusion if you use the wrong "Po." You might be trying to hug your grandma and accidentally insult your mother-in-law.
- Northern China: Uses Lǎolao (Maternal) and Nǎinai (Paternal).
- Southern China/Taiwan: Often leans toward Wàipó or Ā-mā (Maternal).
- Formal Speech: Zǔmǔ (Paternal) or Wàizǔmǔ (Maternal).
The Honorifics You Didn't Know You Needed
Sometimes, you aren't talking to your own grandmother. Maybe you’re talking to a friend’s grandma, or a literal stranger on the street who looks like she’s about 80.
In Chinese culture, calling an elderly woman "Grandma" is actually a sign of huge respect, even if you aren't related. But you wouldn't use the family-specific terms.
If you see an elderly lady struggling with her groceries, you’d call her Nǎinai. It’s the default polite address for a woman of that generation. Using her name would be weird. Calling her "Ma'am" feels too cold. Nǎinai strikes that perfect balance of "I respect your age" and "I see you as a pillar of the community."
But don't call a 50-year-old woman Nǎinai. Seriously. Just don't. You’ll be lucky if you only get a dirty look. For middle-aged women, you stick to Āyí (阿姨), which means "Auntie." The line between Auntie and Grandma is a dangerous one to cross, so when in doubt, go younger.
Deep Nuance: The Power of Tones
We have to talk about the elephant in the room: tones.
Mandarin is tonal. If you mess up the tone for Nǎinai, you might end up saying something that sounds suspiciously like "milk" (Nǎi). While that's technically where the word comes from—linking the grandmother to the provider of milk/sustenance—shouting "Milk! Milk!" at an old lady is going to be embarrassing.
The first syllable of Nǎinai is a low, dipping third tone. You start middle-range, drop deep, and come back up slightly. The second syllable is neutral—short and clipped. Think of it like a basketball bouncing once and then stopping dead.

Lǎolao is similar. Third tone, then neutral.
Wàipó is a different beast. Wài is a sharp, falling fourth tone. It sounds like you’re emphasizing a point. Pó is a rising second tone, like you’re asking a question. Wài-pó? ## Common Misconceptions About Mandarin Grandparents
People often think Chinese culture is rigid and unchanging. That’s not quite true. In modern urban China, especially with the legacy of the One-Child Policy, these distinctions are starting to blur in some families.
Since many kids only have one set of grandparents nearby, they might just use whatever term the family likes best. I’ve met kids who call their maternal grandmother Nǎinai because she’s the one who raised them.
However, if you are learning the language, do not start breaking the rules yet. Learn the "proper" way first. People will appreciate the effort you’ve put into understanding the nuances of their family structure. It shows that you aren't just memorizing words; you’re learning the culture.
Also, don't assume every "Grandma" wants to be called Grandma. In some high-society circles in Shanghai or Hong Kong, grandmothers might prefer more Westernized nicknames or simply their names with a title. But for 95% of your interactions, the traditional terms are king.
Putting It Into Practice
So, you’re ready to actually use this. How do you start?
First, identify which side of the family you’re dealing with. Is it the dad’s side? Use Nǎinai. Is it the mom’s side? Check if they’re from the North (Lǎolao) or the South (Wàipó).
Don't worry about being perfect. Chinese people are generally incredibly forgiving of foreigners trying to navigate their honorifics. In fact, if you use the "correct" term for a maternal grandmother based on her hometown, you will likely win a lot of "brownie points." It shows you did your homework.
Actionable Steps for Learners
- Check the Map: If you're visiting China, find out if you're north or south of the Yangtze River. This dictates whether you should be practicing Lǎolao or Wàipó.
- Record and Listen: Use an app or a site like Forvo to listen to native speakers say Nǎinai. The third tone is notoriously difficult for English speakers because we don't usually go that low in our vocal range.
- Watch C-Dramas: Look for "slice of life" shows. Listen to how the children address the elders. You’ll notice that the terms aren't just labels; they are used as pronouns. Instead of saying "How are you?", a child might say "Nǎinai, is Nǎinai hungry?"
- Avoid the "Grandmother" Trap: Never use Zǔmǔ in conversation. Save it for your flashcards or your history thesis.
Learning how to say grandma in Mandarin is a window into the Chinese soul. It’s about more than just a name; it’s about where you fit in the world and who you belong to. Whether she’s your Nǎinai, your Lǎolao, or your Wàipó, she’s the glue of the family. Use the right word, and you’re already halfway to being part of the inner circle.
